Back when I hand quilted I wasn't too bothered by getting too hot. I wouldn't quilt at the height of summer. I loved in the winter during cool weather. But I see you live in the deep south where it never gets really, REALLY cold. but does get really REALLY hot and humid. I think if I lived in Mississippi I would definitely be bothered by it too. Maybe you can try doing hand quilting quilt as you go so you only have a small size in your hoop and on your lap at any given time.
